Answer:

5 & 6

Step-by-step explanation:

The nearest two perfect squares are √25 and √36 which are 5 and 6

Answer:

Please check explanations

Step-by-step explanation:

To find the volume of the surface area of a cone, we need to use the height and not the slant height of the cone

The slant height, the height and the base radius forms a right triangle with the slant height being the hypotenuse of this triangle

By Pythagoras’ theorem, the square of the hypotenuse (slant height) equals the sum of the squares of the two other sides

6.5^2 = 2.5^2 + h^2

h^2 = 36

h = √36

h = 6 cm

So we have the volume as;

V = 1/3 * pi * r^2 * h

where r in this case is base radius of 2.5 cm

V = 1/3 * pi * 2.5^2 * 6 = 39.3 cm^3

Answer:

Answer:

2.375 pounds.

Step-by-step explanation:

formula: divide the number you need to convert by 16

ex. 38 divided by 16 = 2.375

Answer:

explanation:

thats it

Answer: it is 2 ft

Step-by-step explanation:

because you have to do 12/3 and that equals 4 and then you have to do 4/2 and that equals 2

Answer:

Breadth = 12 m

Step-by-step explanation:

Area of a rectangle is given by the formula,

Area = Length × Width

Value of area and length of the rectangular park has been given in this question.

Therefore, by substituting these values in the formula,

300 = 25 × Width

Width = [tex]\frac{300}{25}[/tex]

          = 12 m

Therefore, width or breadth of the rectangular park will be 12 m.

Answer:

2 hours, 4 hours

Step-by-step explanation:

So lets go over what we know.

There are already 10 worksheets created.

Every 1 hour 3 more are made.

27 worksheets need to be made.

Ok, the first thing we can do is subtract the amount of worksheets needed by the amount we laready have:

27-10

=

17

Now, lets divide the amount of worksheets we still need, by how many we make each hour:

17/3

=

Well, 3 goes into 15, 5 times. Then 2 is left. So we know it takes 5 2/3 hours to create all 27 worksheets.

Looking at the answers, 6 hours, 8 hours, and 10 hours would work. However 2 hours and 4 hours would not work.

Hope this helps! ;)

Answer:

17.5

Step-by-step explanation:

[tex]15^{2}+9^{2}= 306\\[/tex]

[tex]\sqrt{306} = 17.5[/tex]

Answer:

x ≈ 17.5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² = 9² + 15² = 81 + 225 = 306 ( take the square root of both sides )

x = [tex]\sqrt{306}[/tex] ≈ 17.5 ( to the nearest tenth )

The radius of a circle is 7 cm. Find its circumference in terms of π.

Radius (r) of a circle = 7 cm. (Given)

We know,

[tex] \dag [/tex] Circumference of a circle is 2πr.

So, its circumference is 2 × π × 7

Its circumference is 14π cm.

Answer:

Radius (r) of a circle = 7 cm. (Given)

We know,

Circumference of a circle is 2πr.

So, its circumference is 2 × π × 7

Its circumference is 14π cm.

Its circumference in terms of π is 14π cm.

Answer:

Hello! Answer: 496

Step-by-step explanation:

When finding area for triangles we have to do base x height then divide by 2 so

62 x 16 = 992

992 ÷ 2 = 496

So 496 is our answer!

Answer:

A - 496

Step-by-step explanation:

formula for area of a triangle

[tex]a = \frac{bh}{2} [/tex]

where b = base length and h = height

The triangle shown has a base length of 62 ft and a height of 16 ft

That being said we plug in the given values into the formula

[tex]a = \frac{62 \times 16}{2} \\ 62 \times 16 = 992 \\ \frac{992}{2} = 496[/tex]

Hence the area of the triangle is 496 square feet

Answer:

x is 38°

Step-by-step explanation:

180° - 142° = 38°.

Hope this will help❤️

Answer:

x= 154°

I hope it's helps you

Answer:

x=154

Step-by-step explanation:

The figures provides us with a variable and the number 154.

In this situation, the value of x and the given angle are  corresponding angles.

The theorem of corresponding angles states that if a transversal is cut by two parallel lines the corresponding angles are CONGRUENT.

When an angle is congruent, they are equal to each other.

So in this case, x=154, x≅154.

Hope it helps! :)

Answer:

0=3 1=5 3=9

Step-by-step explanation:

Answer:

x = 19

Step-by-step explanation:

The lower base angles in an isosceles trapezoid are congruent , then

5x - 20 = 2x + 37 ( subtract 2x from both sides )

3x - 20 = 37 ( add 20 to both sides )

3x = 57 ( divide both sides by 3 )

x = 19

Answer:

x=2

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

if x^3 is = 8, then

x= ∛8

∛8 = 2

x=2

to check

2*2*2= 8

Answer:

1.75

Step-by-step explanation:

h(t) = -16t² + 56t

h'(t) = -32t + 56

To find time at max height equate h' to 0

0 = -32t + 56

t = 56/32 = 1.75 s

It takes 1.75 s to reach max highest point

Answer:

1) vertical

2) adjacent

Step-by-step explanation:

so, vertical is when two different numbers are congruent and adjacent is numbers next to each other but are no congruent

Answer:

75

Step-by-step explanation:

1. Eliminate wrong answers

a. (boys 5 & girls 4) meaning the boys should have a higher number than girls (which is 60) this meaning that 48 and 61 can not be the correct answer.

5/4=x/60

x=(5/4)*60

x=75

Math rocks

Leaving it to the obvious chose(The answer is 75)
